Problems solved by technology

[0005] However, when organic matter exists on the surface of the glass fiber fabric, the effect of the coupling agent is hindered, and it is necessary to remove the sizing agent that constitutes the source of the organic matter from the glass fiber fabric in advance.
When the sizing agent cannot be completely removed and the silk cloth remains dirty, when used as an insulator, there are problems in the insulation resistance and heat resistance of the insulator

Embodiment Construction

[0038] Next, embodiments of the present invention will be described in detail with reference to the drawings.

[0039] First, an outline of an apparatus for implementing the glass fiber fabric washing method according to the embodiment of the present invention will be described. Such as figure 1 As shown, the glass fiber fabric 2 wound on the first core 1 a is drawn out and conveyed via a plurality of rollers 3 . Then, firstly, the above-mentioned glass fiber fabric 2 is immersed in the washing liquid 5 stored in the washing liquid tank 4 to perform a first washing treatment step. The washing solution 5 contains amylolytic enzymes and nonionic surfactants having two or more different HLB values ​​ranging from 12.0 to 15.5. Thereafter, the glass fiber fabric 2 is wound up on the second core 1b after being dried in the drying step 7 in the second washing treatment step 6 with a washing fluid to remove the sizing agent from the glass fibers.

Abstract

[Problem] To provide a method for cleaning a glass fiber woven fabric, which is capable of achieving an effect equivalent to that of a heat treatment when a sizing agent is removed from the surface of a glass fiber woven fabric. [Solution] A method for cleaning a glass fiber woven fabric, in which two processes, namely a first cleaning process wherein cleaning is carried out with use of a starch degrading enzyme and two or more nonionic surfactants having different HLB values and a second cleaning process wherein cleaning is carried out with use of a cleaning fluid, are performed when a sizing agent is removed from the surfaces of glass fiber filaments.

Description

technical field [0001] The invention relates to a method for washing glass fiber fabrics. Background technique [0002] Glass fibers are used in everything from housing equipment to electronics due to their excellent strength and electrical insulation properties. In particular, glass fiber fabric has very excellent electrical insulation properties, and is used as a printed wiring board material in which epoxy resin and polyimide resin are combined. [0003] The glass fiber fabric can be obtained by weaving glass fiber bundles as described below. First, the surface of glass fiber filaments obtained by spinning molten glass is coated with a sizing agent and bundled to form a fiber strand. Next, the fiber bundle is further coated with a sizing agent to prevent yarn breakage, fluffing, etc. before weaving. The sizing agent used in these steps is based on starch and oil agent. [0004] The glass fiber fabric is applied to FRP, an insulator of a laminated printed circuit board...
